You can implement the Cortex-R7 MPCore processor with an optional ETM. If the ETM is present, there is a dedicated ETM and AMBA Trace Bus (ATB) interface, see ETM/ATB interface signals. The ETM provides instruction and data trace for the processor. For more information on the ETM itself, see the ARM® CoreSight™ ETM-R7 Technical Reference Manual.

The ETM/ATB interface confirms to the AMBA ATB specification. The ETM/ATB interface includes the following signals:
